燃城市煤气的空气喷射式无焰烧咀,在国外已普遍使用,它最适合于燃烧城市煤气、天然气等发热量高的煤气,适合于小型加热炉及热处理采用。在沈阳市弹簧厂汽车板簧淬火炉上初次使用,经四年的生产实践证明,燃烧完全,要求助燃空气过剩系数小,燃烧速度快,加热时间短,因而提高了炉子产量,降低了燃料消耗;炉温均匀,改善了加热质量。一、淬火炉概况板簧为60Si_2Mn弹簧钢,工艺要求淬火炉金属加热温度为930—950℃,板簧长度上温度要均匀。步进炉长度4,919毫米,宽2,083毫
Burning city gas air jet flameless Tsui has been widely used abroad, it is most suitable for burning city gas, natural gas and other high-calorie gas, suitable for small furnace and heat treatment used. It has been used for the first time in Shenyang spring plant automobile leaf spring quenching furnace. After four years of production practice, it has been proved that the combustion is complete, the excess coefficient of combustion air is required to be small, the burning speed is fast and the heating time is short, thus increasing the furnace output and fuel consumption ; Uniform temperature, improve the heating quality. First, the quenching furnace Overview Spring is spring steel 60Si_2Mn, quenching furnace process requires metal heating temperature 930-950 ℃, the length of the leaf spring temperature should be uniform. Stepper length 4,919 mm, 2,083 mm wide
